The lower ends of the rake bars are preferably bent outwardly. As shown each'rake bar is composed of two sections, the. lower Figure 1 is a plan view of the machine; Fig. 2 is a side elevation, partly in section, taken on the line 2-2 of Fig. 1; Figs. 3, 4, 5, 6 and 7 are details of various parts.

The invention is illustrated in connection with a machine of the type shown in Patent No. 378,466 to Slaght. The machine is provided with a rectangular frame 10, carried by traction wheels 11, 12., A deck 13 is piv- 15, carried by a pair of super frames rising from the frame 10 and, as shown, each com.- prising an upright 16, 17, and a cross-member18. There being a super-frame at each side of the machine, but one is shown in detail. Braces 19 are pivotally attached to the forward end of the frame 10, one at each side, and are removably engaged with the deck 13, as shown, entering socketlates 20 secured to the sides thereof. A cy inder 21 1 is journaled in a pair of adjustable brackets 22, pivoted on the axles of the wheels 11 and I 12, and cooperating with a quadrant 23 on l theuprights 17 of the super-frames. l The cylinder 21 is provided with rake teeth 24, preferably reciprocally mounted. Inasmuch, however, as this feature is not an essential part of the invention and is old and l well known in the art, I have not deemed it 1 a late 47 carried by the upper section of the necessary to show it in detail. The cylinder ra e-bar; this plate having a plurality of 21 is driven through the medium of;,gear pin-holes 48 longitudinally arranged, thereby wheels 25, fixed upon the axles of'the carry.- l providing for an adjustable connection of the naled on the rake-bar, and at its upper end to proach and move up shorter section, as 44, being hinged, as shown,v

The rake teeth 49 in the lower sections of the rake-bars, and 50 in the lower portions being carried at their upper ends by a swinging frame 64, pivoted at 65 to the side rails of the deck 13 and guided in loops 66 rising therefrom, the lower ends being guided in 5 suitable loops 67 mounted. in any desired 70 of the upper sections thereof are preferably manner, as shown rising from a cross-bar 68 fixed, while the teeth 51 in the upper porcarried by the frame within which the rail 27 tions of the upper sections of the rake-bars is journaled. are pivoted in such manner'that they may The action of the machine is as follows fold upwardly hen each rake-bar has The hay being first collected by the gather- 75 reached the limit of its upward movement ing device, in the present instance the cyl- 1ts lower end 1s moved outwardly, thereby inder 21, and brought into the zone of action withdrawing the teeth from the hay, while of the lower end of the rake-bars 30 to 33, is the teeth of the advancing rake-bars are enseized by the advancing bars, and comtering it.

This mounting tached to a wagon, and the upper ends of the of the loops 34 holds the upper ends of the rake-bars 30 to are preferably provided oppositely disposed rake bars sufficiently with longitudinal loops 70 which play within 35 c ose together to insure engagement with the the loops 34..
